Name

split — split a file into pieces

Synopsis

split [OPTION...] [ FILE [PREFIX] ]

DESCRIPTION

Output pieces of FILE to PREFIXaa, PREFIXab, ...; default size is 1000 lines, and default PREFIX is 'x'.

With no FILE, or when FILE is −, read standard input.

Mandatory arguments to long options are mandatory for short options too.

−a, −−suffix−length=N/

generate suffixes of length N (default 2)

−−additional−suffix=SUFFIX/

append an additional SUFFIX to file names

−b, −−bytes=SIZE/

put SIZE bytes per output file

−C, −−line−bytes=SIZE/

put at most SIZE bytes of records per output file

−d

use numeric suffixes starting at 0, not alphabetic

−−numeric−suffixes[=FROM/]

same as −d, but allow setting the start value

−x

use hex suffixes starting at 0, not alphabetic

−−hex−suffixes[=FROM/]

same as −x, but allow setting the start value

−e, −−elide−empty−files

do not generate empty output files with '−n'

−−filter=COMMAND/

write to shell COMMAND; file name is $FILE

−l, −−lines=NUMBER/

put NUMBER lines/records per output file

−n, −−number=CHUNKS/

generate CHUNKS output files; see explanation below

−t, −−separator=SEP/

use SEP instead of newline as the record separator; '\0' (zero) specifies the NUL character

−u, −−unbuffered

immediately copy input to output with '−n r/...'

−−verbose

print a diagnostic just before each output file is opened

−−help

display this help and exit

−−version

output version information and exit

The SIZE argument is an integer and optional unit (example: 10K is 10*1024). Units are K,M,G,T,P,E,Z,Y (powers of 1024) or KB,MB,... (powers of 1000).

CHUNKS may be:

N

split into N files based on size of input

K/N

output Kth of N to stdout

l/N

split into N files without splitting lines/records

l/K/N

output Kth of N to stdout without splitting lines/records

r/N

like 'l' but use round robin distribution

r/K/N

likewise but only output Kth of N to stdout
